Setting up color balancing

You can set up color balancing by using any of the following methods:

Note: At this time, the color balancing you specify applies to all source images. If you want to apply color balancing to an individual image, or a group or range of images, you can do so in the Mosaic Tool window after you generate the mosaic preview. For more information, see Performing color balancing.

To set up color balancing

Make sure the Apply color balancing check box is selected.
In the Method list, select from the following the method to use to compute cutlines:
- None
- Bundle
- Histogram
- Overlap area
- Reference image
- Neighborhood
Do the following, based on your selection in the Method list:
- None: Proceed to step 5.
- Bundle: To apply linear stretching and a common scale, select the Autoscale check box.
  Autoscale can improve the results when different input images have significantly different dynamic ranges.
- Histogram: To use a match area, type the percentage value you want in the Match area box. To apply tail trimming, type a percentage value in the Tail trim box.
- Overlap area: Proceed to the next step.
- Reference image: In the Reference image box, type the path and file name of the reference image you want or, to select an image, click Browse.
- Neighborhood: Proceed to the next step.
To use a global mask, beside the Global mask box, click Select, and then select the file containing the global-mask layer you want.
To use a local mask, in the Local mask list, select from the following according to the type of mask you want:
- None: All pixels through which a cutline can pass are valid candidates.
- Last vector: Sets the last-created vector segment in the source image as the mask layer.
  When no vector segment exists, all pixels through which a cutline can pass are valid candidates.
- Last bitmap: Sets the last-created bitmap segment in the source image as the mask layer.
  When no bitmap segment exists, all pixels through which a cutline can pass are valid candidates.
- Specific segment: Defines a specific segment in the source image as the mask layer.
  When you select this type of local mask, enter the segment number in the Segment number box.
Proceed to Setting up the sort order.
